Application tiled April 26, 1919.

To all whom it may concern Be it known that I, ARTHUR E. SWEET, acitizen of the United States, and a resident of the city 4of Portland,in the county of Multnomah and VState of Oregon have invented a certainnew and useful Oil-Burner, of which the following is a specication.

My invention relates more particularly to that class of devices whichpermit the burning of a liquid fuel in the ordinary cook stove, heateror furnace.

The object of my invention is to provide an exceedingly simple, safe,noiseless, eilirient and convenient means for converting kerosene andcheaper.oils into a -properly l mixed gas for heating and coo-kingpuroses. l p It being a. well known fact that existing devices for theabove mentioned urposes are noisy, dangerous and more or ess diiiicultto operate, which objections I have overcome in the manner illustratedin accompanying drawing and explained in the specilcation following.

Referring to the drawing, Figure 1 is a front elevation of my device ofwhich Fig. 2 is a sectional elevation along the line 2--2 in Fig. 3.Fig. 3 is a plan; Fig. 4 is a detail in plan showing the burner capmoved to one side and exposing the gas outlet. Fig. 5 is a partialbottom view showing the means for regulating the mixture.

Similar letters and numbers of reference refer to the same or similarparts throughout the several views.

On the flat base A1 are formed the walls A2 which form the lighting cupA, in the Hoor of which is located the oil inlet hole A4. On the base A1are also positioned the lugs A which serve to support the piping. A6 isa clamp which holds the piping against the lugs A5, said clamp beingheld in place by the screws A. As 1s a baille plate which is suspendedfrom the overhead pipin by the hook A". A1 is asbestos packing w osefunction it is to exclude all air from the combustion which does notpass through the mixer.

F1 is a generating pipe which is closed at one end by the plug F2 whichmay be removed for cleansing purposes. The end Fa of the generating pipeF1 is joined to an oil supply pipe. F* is a gas outlet hole w ic isformed in the enerating ipe F1. F5 are coils formed in ille generatiiigpipd Specification of Letters Patent. i Patented Oct. 14, 1919.

ing to expose a greater area to the actionof the heat. Over the gasoutlet hole F4 is placed the gas and air mixing chamber F, underneathwhich and extending through the base A1 are the holes F7 which admit airto the jet of gas escaping from the hole F 4 andwhich holes may beclosed as desired by the cover FB which rotates on thel -pivot F9 and isoperated by the handle F10. It Ibein understood that the cover F s issup.n plie with the holes F11 which correspond with -the holes F" sothat the openings F may be entirely uncovered if desired. F12 is adepression in the base A1l for receiving the gas and air mixing chamberSaid caplis cut away at F13 for the pipe F1.

1 is a ressure oiltank on which is the gage H2. Il-Is is an oil sup lpipe leading from the tank H1 to the 'lpfitting H4. I -I5 is an oil lineof small pipe leading from the T H4 to the inlet hole A4 in the lightingcup A3. The lflow of oil for generating purposes is re lated by theneedle valve I-I1 in the pipegli. This valve is of course used only forstartin purposes. From the T H1 extends the oil Supply pipe H7 which isjoined to the pipe end F3, which pipe H7 is supplied with the needlevalve H8 which regulates the flow of oil to the generator pipe F1.

By means of the construction thus described, I entirely eliminatebackliring, noise, danger from explosion and the usu-al inconvenience ofstarting. I am also able to secure a great range of temperature as Wellas to insure a uniform application of heat to the stove oven.

The stove walls are indicated at K1 while the stove grate is indicatedas K2.

While I have thus illustrated and described my invention it is not myintention to limit myself to this precise form or method of applicationof my invention but intend that it shall cover all forms andmodifications that fall fairly within the appended claim.

What I claim as new and desire to protect by Letters Patent of theUnited States isz' In an oil burner, the combination of a base plateadapted to rest on the grate of a stove 1n a manner to exclude all ofthe air from passing around the base plate, a lighting cup formed onsaid base plate, a generatin means consisting of a coil of pipe secureabove' said base plate, said pipe having a gas UNITED sTATEs PATENToEE1oE.
